A ring of asteroids containing perhaps thousands which measure several kilometers in diameter, and millions of which measure several meters in diameter or smaller. The asteroids travel in orbits between 2 and 3.5 A.U. from the Sun, locating them between the orbits of Mars and Jupiter.

A ring of asteroids containing perhaps thousands of big rocks several kilometers in diameter, and millions of smaller chunks. Asteroids orbit between 2 and 3.5 AU from the Sun, between the orbits of Mars and Jupiter.

A ring of asteroids which lies between the orbits of Mars and Jupiter. After the space settlement program is launched in the early years of the Universal Century, some of these asteroids are transferred to Earth orbit to supply resources for colony construction. The Principality of Zeon also establishes a permanent outpost at one of these asteroids, and this Axis base becomes a place of refuge for the Principality's defeated soldiers after the end of the One Year War.

the area of space in our solar system between Mars and Jupiter where the majority of the asteroids are found. It is believed that a planet would have formed here if not for Jupiter's strong gravitational affects disrupting the planets formation

The region of the solar system between the orbits of Mars and Jupiter in which most asteroids are located. The main belt, where the orbits are generally the most stable, extends from 2.2 to 3.3 AU from the Sun.

The region between 2.1 and 3.5 astronomical units (AU) from the sun where most of the asteroids are found. Asteroids are small planetary bodies revolving around the sun; most of the orbits are between the planets Mars and Jupiter.
